Definitions

  • the invention relates to a fuel supply device, in particular for the combination with a rotor-carburetor system of an internal combustion engine.
  • Rotor carburettors have been described in the following patents: US 3,991,144 US 261 / 36A; 261/63 U.S. Patent 2,823,906 U.S. Patent 4,044,081 Int.CI F02M 37/04
  • the object of the present invention was to provide a simple and inexpensive fuel supply device which makes it possible to drive with a very precise fuel-air mixture in all working areas of the internal combustion engine.
  • the inventive solution to the problem consists in the fuel supply device defined in the characterizing part of claim 1.
  • a fuel supply device With a fuel supply device according to the present invention, it is possible to achieve the correct fuel-air mixture in all driving ranges of the internal combustion engine, such as warm start, acceleration and full load, without electrical aid using a rotor-carburetor system.
  • the required fuel enrichment can only be achieved by energizing an electromagnet only when cold starting from -10 to -20 ° C.
  • FIG. 1 A preferred embodiment of the invention is illustrated in the accompanying drawing, the single figure of which shows a longitudinal section through a fuel supply device combined with a rotor-carburetor system.
  • the combination of a fuel supply device with a rotor-carburetor system shown in the drawing has a cylindrical rotor body 2, which is fastened in the housing 1.
  • the five-lipped wing 3 is pressed onto the rotor axis 4.
  • the vane 3 and thus the rotor axis 4 rotate in the ball bearings 5 and 6.
  • the centrifugal seal 7 is located between the inlet pipe 9 and the vane axis 4.
  • the fuel flows through the centrifugal bore 8b to the riser bore 8a.
  • the fuel flows through the ruby nozzle 10 to the spray ring 11.
  • the spray ring 11 ensures a fine spraying of the fuel.
  • Port 15 is connected to a gasoline pump with a pressure of 0.5 to 1 bar.
  • the return 16 leads the excess fuel back to the fuel tank.
  • the chamber 33 is connected via the connection 18 by means of a vacuum hose to the connection 13 of the intake manifold of the internal combustion engine.
  • the negative pressure in the intake manifold of the internal combustion engine when idling is approximately 0.65 bar.
  • the negative pressure in chamber 33 is thus 0.65 bar.
  • the springs 23 and 35 are set so that they are connected to the magnet armature 27, the intermediate piece 26 Valve slide 22, the ball 16 and the plunger 20 act on the membrane 19 such that small gaps are formed between the ball seat 21b, the ball 21a, the valve slide 22 and the bore 25.
  • the electromagnet consisting of coil 30, core 29 and armature 27, the position of the membrane 19 can be changed via the intermediate piece 26 and thus the ball 21a and the valve slide 22 can be changed via the plunger 20. Due to the excitation of the magnetic coil 30, the armature 27 presses the membrane 19 and thus the ball 21a and the valve slide 22 downward via the intermediate piece 26. The gaps between the ball 21a, the ball seat 21b, the valve slide 22 and the bore 25 become larger.
  • the above-mentioned electromagnetic change can also be used for the temperature change occurring in the internal combustion engine.
  • This electromagnet effect can also be used for control with a Lamda probe.
